Well… It works, but a couple of notes (mostly to myself, but, experts, feel free to weigh in) for the future:
Don’t lead with the “@adventuregames” tag. It’s messy.
Keep titles short, 'cos it copies the contents of the post as the title.
Figure out if there’s a way to split title and post content in the Mastodon toot, so the post content isn’t just a copy of the title.
I can’t edit the post after the fact ('cos my Mastodon user and Lemmy user are, as far as this platform is concerned, two different people), and I’m worried if I edit the toot on Mastodon, it’ll just post a new thread here instead of editing the existing one.
